Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a stirring mechanism for wastewater treatment. Background Technology

[0002] Wastewater recycling and reuse typically involves physical, chemical, and biological methods to purify the wastewater, reduce pollution, and achieve wastewater recovery and reuse, thus minimizing water waste. Wastewater treatment usually requires stirring to ensure thorough mixing and reaction with chemical agents, promoting the mixing and dispersion of liquids, gases, and solids in the wastewater, thereby improving water quality and treatment efficiency. A search of Chinese patents revealed publication number CN216785867U, which discloses a stirring mechanism for wastewater treatment equipment. The mechanism includes a stirring tank and a user device. The user device comprises a support leg, a motor cover, an inlet pipe, an outlet pipe, a motor, a rotating rod, a partition plate, an inclined seat, a filter screen, a first set of stirring blades, a second set of stirring blades, a filter cylinder, a solid-liquid separation layer, an activated carbon adsorption layer, and a purification filter element layer. One side of the stirring tank is fixedly connected to the support leg, and the top of the stirring tank is fixedly installed to the bottom of the motor cover. By configuring the support leg, motor cover, inlet pipe, outlet pipe, motor, rotating rod, inclined seat, first set of stirring blades, and second set of stirring blades, the user pours wastewater into the stirring tank through the inlet pipe. Starting the motor drives the rotating rod, which in turn drives the first and second sets of stirring blades to stir the wastewater. The multiple stirring units improve stirring efficiency and facilitate the treatment process.

[0003] Existing mixing mechanisms are inconvenient for replacing the mixing head. Generally, the mixing head and the rotating shaft are fixed together with bolts. Replacing the mixing head requires tools for disassembly and assembly, which is cumbersome, increases workload, and reduces replacement efficiency. Furthermore, the length cannot be adjusted, as the rotating shaft length of most mixing mechanisms is fixed and difficult to adjust for wastewater tanks of different depths. When mixing in treatment tanks of different depths, the corresponding mixing mechanism needs to be replaced, increasing operating costs and reducing practicality and applicability. To address these problems, we propose a mixing mechanism for wastewater treatment. Utility Model Content

[0004] The purpose of this invention is to provide a stirring mechanism for wastewater treatment, which has the advantages of easy replacement of the stirring head and adjustable length.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stirring mechanism for wastewater treatment, including a mounting base, a stirring head slidably sleeved on the inner wall of the mounting base, an adjusting thread on the surface of the mounting base, a fixed shell threadedly connected to the adjusting thread, a sliding cylinder slidably sleeved on the inner wall of the fixed shell, and the sliding cylinder slidably sleeved on the surface of the mounting base, a first spring provided between the sliding cylinder and the inner wall of the fixed shell, and the first spring sleeved on the surface of the mounting base, a plurality of trapezoidal grooves provided on the inner wall of the sliding cylinder, a locking rod slidably sleeved on the inner wall of the trapezoidal grooves, a limiting plate fixedly sleeved on the surface of the locking rod, a second spring provided between the limiting plate and the inner wall of the mounting base, and a plurality of locking holes provided on the surface of the stirring head, and the locking holes locking with one end of the locking rod.

[0008] By adopting the above technical solution, the length of the rotating shaft can be adjusted by loosening the nut, removing the fixing pin, moving the telescopic shaft to the required position, inserting the fixing pin, and tightening the nut. This reduces the cost of use and improves practicality and applicability.

[0009] The present invention is further configured such that: the surface of the mounting base is threaded with a threaded ring, and the threaded ring is located at the top of the fixed shell.

[0014] By adopting the above technical solution, both ends of the locking rod are made of arc shape, which facilitates operation and ensures stability.

[0015] The present invention is further configured such that the surface of the telescopic shaft is printed with scale lines.

[0016] By adopting the above technical solution, the length can be easily adjusted by setting scale lines.

[0017] The present invention is further configured such that a protective shell is bolted to the top of the fixing plate, and the motor is located on the inner wall of the protective shell.

[0018] By adopting the above technical solution, the motor is protected by setting up a protective shell.

[0019] The present invention is further configured such that the surface of the fixing plate is provided with a plurality of mounting holes.

[0020] The above technical solution facilitates installation and fixation by providing mounting holes.

[0021] In summary, this utility model has the following beneficial effects: 1. This utility model moves the trapezoidal groove by moving the sliding cylinder.
